Supreme Court Considers Mail-in Voting Restrictions

Supreme Court's conservative majority appeared ready to overturn laws in 29 states allowing mail-in votes counted after Election Day if postmarked by Election Day.

Objective Facts

The Supreme Court heard arguments in a case testing whether states should be allowed to count ballots mailed on time but arriving after Election Day. The case, Watson v. Republican National Committee, involved a majority of justices seemingly agreeing that Mississippi's law conflicts with federal laws setting the Tuesday after the first Monday in November as "election day." The conservative majority seemed ready to overturn laws in 29 states allowing mail-in votes to be counted after Election Day if they were postmarked by Election Day. A decision is expected by late June or early July. Mississippi's legislature in 2020 approved a five-day grace period for counting election ballots if they were postmarked by Election Day but arrived late.

Left-Leaning Perspective

Critics say Republicans are trying to suppress the votes of people likely to support Democrats, with voting rights lawyer Marc Elias arguing that "they're trying to kick out of the electorate voters who they would rather not have participate in the election." Opponents warned that the ruling could disenfranchise many of the roughly 50 million Americans who voted by mail in 2024. A rigid Election Day receipt rule would curtail states' ability to design election systems that meet local needs and would increase the risk of disenfranchisement, particularly for voters with disabilities, older voters, rural voters facing mail delays, and workers whose jobs require travel. Liberal Justice Ketanji Brown Jackson argued that "it seems to me that we have a very long history of states having a variety of different ballot receipt deadlines, to include after Election Day." Liberal justices said the question is whether Congress has specifically preempted states from allowing post-Election Day grace periods, noting that the text of the federal statutes gives them little to go on. Mississippi's attorney argued that tossing out post-election ballot receipts could jeopardize other functions election officials have conducted for decades after the formal Election Day, noting that the Trump administration's position about early voting being acceptable was a "challenging question." The DNC Chair Ken Martin stated that "Republicans' relentless assault on mail-in voting is not just un-American, but will harm our service members and their families who have risked it all for our democracy," and "The DNC refuses to sit idly by while Donald Trump and the RNC try to silence voters and attack our electoral system." Left-leaning outlets frame this as a partisan power grab targeting Democratic-leaning voters, emphasizing potential disenfranchisement of vulnerable populations and military families. They largely omit Republican arguments about election security and the meaning of federal Election Day statutes.

Right-Leaning Perspective

The RNC argues that this practice violates federal law and undermines confidence in elections. Their argument is that for more than a century, federal law has said there is a national Election Day for the House, Senate and presidency, and if they want fair and secure elections, then Election Day should mean exactly what it says. With Watson, the RNC is arguing for enforcing the law, stopping the confusion of elections that drag on for weeks. Jason Snead, executive director of the Honest Election Project, said that requiring Election Day mail-in ballot deadlines is a "very popular position with the voters" and "a best practice as far as election administration is concerned," emphasizing that "everybody understands that the ballot is really considered a vote when it's received by an election official." Justice Samuel Alito expressed concerns about a critical mass of mail-in ballots arriving after Election Day undermining confidence in election integrity, noting that briefs argued "confidence in election outcomes can be seriously undermined if the apparent outcome of the election on the day after the polls close is radically flipped by the acceptance later of a big stash of ballots that flip the election." The Trump administration told the Supreme Court that "Election-day receipt promotes election integrity and voter confidence as much today as it did when Congress passed that law." Solicitor General John Sauer argued that "Ensuring all ballot boxes close on the same day eliminates incentives and opportunities for fraudulent abuse" and that "Leaving them open conflicts not only with the ordinary meaning of 'election day,' but also with the very integrity of the election." Right-leaning outlets and Republicans frame this as enforcing existing federal law and promoting election integrity through clarity and finality. They emphasize historical practice and the need for definitive election closure, arguing that late-arriving ballots create opportunities for fraud and undermine public confidence. However, they largely downplay or omit testimony from Mississippi officials and left-leaning commentators that no fraud from post-Election Day receipts has been documented.

Deep Dive

Mississippi passed the grace period law in 2020 in response to the COVID-19 pandemic, allowing five days for mail-in ballots to arrive if postmarked by Election Day. The Republican National Committee, Mississippi Republican Party, a Mississippi voter, and the Libertarian Party challenged the law in 2024, arguing it clashes with a federal law enacted by Congress in 1845 establishing the Tuesday after the first Monday in November as "election day," with Congress directing in 1872 that congressional elections should occur on this day as well. This case sits at an intersection of constitutional federalism, statutory interpretation, and practical election administration—but it reflects broader Republican efforts to restrict voting methods that demographically benefit Democrats. Both sides present coherent legal theories but emphasize different aspects of history and practice. The right argues from a literal reading of federal Election Day statutes combined with 19th-century historical practice when ballots had to be physically delivered on Election Day. The left counters that Congress has legislated around state grace periods for decades without explicitly overturning them, and that modern mail delivery times make same-day receipt impossible for many voters. Even election law scholars acknowledge the court is closely divided and could rule either way. A genuine tension exists: Conservative justices raised concerns about how their logic would foreclose early voting and other modern election practices, and there was little attention during the hearing to the risk of confusing voters during November's election with a ruling striking down Mississippi's law. What remains unresolved is whether conservative justices' apparent concerns about mail-in ballot practices more broadly—including who can receive a ballot, whether it must be postmarked, and whether states may allow ballots to be recalled—signal willingness to challenge other voting practices beyond grace periods. Election officials warned that eliminating post-election ballot receipt deadlines would affect nearly every aspect of preparation and administration of the general election in these states in 2026, just months before it is set to occur. A June or early July ruling would force rapid changes across affected states during midterm preparations, creating the kind of election-year uncertainty courts typically seek to avoid.

What's Going On

The Supreme Court heard arguments in a case testing whether states should be allowed to count ballots mailed on time but arriving after Election Day. The case, Watson v. Republican National Committee, involved a majority of justices seemingly agreeing that Mississippi's law conflicts with federal laws setting the Tuesday after the first Monday in November as "election day." The conservative majority seemed ready to overturn laws in 29 states allowing mail-in votes to be counted after Election Day if they were postmarked by Election Day. A decision is expected by late June or early July. Mississippi's legislature in 2020 approved a five-day grace period for counting election ballots if they were postmarked by Election Day but arrived late.

Left says: The case is part of the broader GOP effort, led by President Donald Trump, to restrict mail voting out of belief that it helps Democrats. According to voting rights lawyer Marc Elias, Trump wants Election Day voting only in-person, and eliminating vote-by-mail is the most convenient way to start but not where they will end.
Right says: Republicans argue that for more than a century, federal law has said there is a national Election Day, and if the country wants fair and secure elections, then Election Day should mean exactly what it says. The RNC stated that Watson v. RNC is about a simple principle that ballots must be received by Election Day to prevent elections from dragging on for days and weeks after voters cast their ballots, causing confusion and undermining elections.
✓ Common Ground
Both the RNC and the Trump administration agree that the Election Day law prevents late-arriving ballots but does not bar early voting.
There is agreement among some observers that the Supreme Court will be closely divided on this case, with scholars noting it could come out either way.
Both sides acknowledge that there have been no documented instances of fraud from post-Election Day ballot receipts, with Mississippi Solicitor General Scott Stewart noting his opponents "haven't cited a single example of fraud from post-Election Day ballot receipts."
Across the political spectrum, there is recognition that approximately 30% of voters cast mail ballots in 2024, demonstrating widespread reliance on this voting method.

◈ Tone Comparison

Left-leaning outlets use charged language framing the case as an "assault" or "brazen effort" to suppress Democratic voters, emphasizing partisan motivation and disenfranchisement risks. Right-leaning outlets employ neutral-sounding legal terminology like "enforcing the law," "election integrity," and "security," presenting the case as a straightforward constitutional matter about federal Election Day statutes. The disagreement over framing extends to whether late-arriving ballots pose legitimate integrity concerns (right) or represent unfounded partisan fearmongering (left).

✕ Key Disagreements
What Election Day statutes mean historically
Left: Liberal Justice Ketanji Brown Jackson argued that states have "a very long history of states having a variety of different ballot receipt deadlines, to include after Election Day."
Right: Republicans argue that for more than a century, federal law has said there is a national Election Day and that if the country wants fair elections, Election Day should mean exactly what it says.
Whether Congress needed to explicitly restrict post-Election Day deadlines
Left: Mississippi argues that Congress has not acted to prevent states from using grace periods, so Congress clearly has no problem with it, and if Congress thinks votes need to be received by Election Day to count, they could change the law—making it a question for the elected branches, not unelected judges.
Right: RNC lawyer Paul Clement argued that when Congress passed the law establishing Election Day, the casting of ballots and the state's receipt of ballots were "so inextricably intertwined" that "no one would have thought of one without the other."
Whether late-arriving ballots threaten election confidence
Left: Mississippi Solicitor General Scott Stewart stated that his opponents "haven't cited a single example of fraud from post-Election Day ballot receipts" and that "I don't know that people have that particular concern. I think obviously people can be unhappy when a result flips."
Right: Briefs submitted to the court argued that "confidence in election outcomes can be seriously undermined if the apparent outcome of the election on the day after the polls close is radically flipped by the acceptance later of a big stash of ballots that flip the election."
The strategic intent behind the lawsuit
Left: Trump vowed to end mail-in ballots before the 2026 midterms, a move that likely would disproportionately benefit his party given that Democratic voters traditionally have been more likely to use mail-in ballots than Republican voters.
Right: The RNC emphasized building on election integrity success from 2024 and stated the case is about enforcing existing law and election security, not partisan advantage.
